The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for the next stretch. Honestly, for a solid week and a half, it’s gonna be a tough sit. We’re looking at a real dry spell before anything worth paddling out for shows up.

The water temp at Kennebunk Beach is sitting at 64°, which is a touch warmer than normal for this time of year, so at least the first few days of waiting won’t be too chilly.

Right now, from Thursday the 10th all the way through to Monday the 21st of September, it’s just not on. Swell is tiny, mostly under 3 ft, and when we do get a little bump, the wind is all over the place. The combined energy is weak, mostly under 100, and the forecasts are all marked as poor. There’s a glassy morning on Friday the 11th, but with only 1 ft of south-east swell, it’s a flat, wobbly nothing. Even Sunday the 13th sees a bump to 5 ft, but it’s a short-period, sloppy south swell with onshore wind, making it a messy, choppy mess. That’s a no-go.

By Tuesday the 22nd of September, things finally get interesting, but it’s for the experts only. A serious east-nor’easterly swell is forecast to push through with a height of 12 ft, period around 10 seconds, and a massive combined energy of 3671. The wind is fresh offshore from the ENE, which should keep it pretty clean. But I can’t sugarcoat it – that’s big, powerful stuff. Only for the experienced crew. The morning is the standout, with that offshore wind and a solid wall of water. The afternoon drops a bit to 8 ft, still hefty but less energy.

After that, Wednesday the 23rd and Thursday the 24th settle down to about 4 ft from the south-east, but the wind is mostly cross or cross-on, and the quality drops off again. It’s not worth the paddle.

Then on Friday the 25th of September, there’s a flicker of hope. The morning shows 6 ft of south-east swell with a period of 8 seconds, combined energy of 469, and a light offshore wind from the ENE. The forecast says “expect good surf conditions,” but it’s still a bit short-period. The afternoon, the wind swings onshore and ruins it. So if you’re going to pick a day, that Friday morning is the best bet, but it’s not a world-beater.

Overall, this forecast is a marathon of waiting. The first real, rideable swell is over a week away, and even then, it’s either too big for most or only barely clean. It’s one of those stretches where the ocean is just not playing ball.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
